1 Claims. (01. 4-221) The invention concerns a device adapted to beinstalled in the conventional tank of a, closetin order that uponoperation of the flushing valve a cleansing and deodorizing solutionwillauto matically be fed into the stream of water discharged into thebowl. The'entrained solution enables the bowl to be kept in a clean anddeodorized condition.

The invention has. for itsobject to produce a device so constructed andarranged that a submerged reservoir'is filled with Water from the tanksupply and forced upwardly by an air trap so as to impinge an elevatedchemical compound in the form of a cake or mass. The chemical compoundis composed of well known ingredients which are for the purposeof thisinvention combined into a loosely packed cake or brick so that theelevated water will partially disintegrate .it and thus form a solution.The solution is caught in a chamber provided with a'syphon which.automatically discharges a portion .of it down the usual overflow pipeupon foperation of the flushing valve-of the tank. l I

A distinctive. advantage of the invention is-that it is entirelyautomatic. in itsoperation and that it has no moving parts-thatare-likely to get out of order. The device is inexpensive tomanufacsure,and a cake orbrick'of the chemical compound will last foraconsiderablelength of time before having to be replaced.

V Likenumerals of reference indicate corresponding partsv in each of thefigures throughout the drawings of the invention. v I a In describingthe invention ingreater detail, the gprefrerred form showni-n Figures 1to 4; in elusive will first be recount-ed;

The'reference numeral 8 denotes .a standard flush tank which is mountedabove the bowl ofa closet for discharge through the flushconnection 9provided with the usualfloat valve ll] of which this arrangement thesolution is drawn off from the rubber float l'l forms a part. The .floatof course is tripped in well known manner each time. the bowl (notshown) .is to be flushed.

The regular overflow pipe is shown at l 2, which pipe communicates atits base with the'flush 5 connection for the purpose of taking care ofundue rise in the level of the Water contained in the tank, andcontrolled by the ball-cock, which is not shown since it does not form apart of the present invention. The normal level of the 10 water in thetank is denoted at I3.

The device of the present invention is suitably supported in the tankalongside of the overflow pipe 12 .and comprises a cup-shaped chamber orsolution receptacle I4 of whichthe open top If supports a perforatedplate I6. A convenient expedient for supporting the plate consists of anannular ledge -Ifl inside the top of the chamber and formed by crimpingthe metal sidewall thereof. V The plate rests upon the ledge H in order.to seat thechemical compound which is in the nature of a cake or brickl8 as aforesaid. The plate preferably has a large central hole [9encompassed by several small holes as at 20..

A .tubular cylinder 2| is attached to and depends from the bottom of thesolution receptacle I4. The upper end of the cylinder is closed by thereceptacle. The lower end'however is'open and disposed in spacedrelation to the floor of 30 the tank. The cylinder constitutes an airtrap as will be later explained.

Wi'-thin the cylinder and spaced from its top is a. cup 22 of a smallerdiameter than the cylinder bore so as to provide an intervening passage23 {55 The cup is rigidly attached by suitable means such as denoted at24.

Vertically mounted in the cylinder is an eduction tube 25 having itslower end open and disposed within the cup 22 at a distance from itsbottom. The tube extends upwardly through the solution receptacle l4 andterminates in an open top slightly below the plate l6 in alignment withthe central opening I9 therein.

The solution receptacle is furnished with a. syphoning tube 26 laterallydisposed with the short end protruding downwardly through the upper part.of the sidewall and the long end projecting. into the Yoverfiow pipe.l2 for emptying therein. The short end is fitted in a duct 21 verticallyarrangedand in communication with the interior of the solutionreceptacle by means of the aperture 28 at the bottom thereof. By

the bottom of the receptacle where it is better commingled.

Having described the invention, its operation will now be recounted:Following the installation of the device, the initial filling of thetank serves as a primer for the cup 22 so as to fill it with water. Itwill be understood that in this initial filling, the water in rising toits usual level, indicated at I3, will freely rise in the cylinder 2|and thus fill the cup 22. The water within the cylinder flows out in theflushing of the bowl. As the tank refills and the water level risesabove the lower end of the cylinder 2|, it

exerts pressure upon the air trapped therein, which is sealed off by theWater in the cup. As

the pressure increases with the rise of the water in the tank, the waterheld in the cup is subjected to sufficient pressure to expel it throughthe eduction tube 25 along with the entrained air. As the educted wateremerges from the top of the tube it sprays upon the bottom of thechemical compound causing partial disintegration that results in asolution that is caught in the chamber [4.

The device is so proportioned that several flushes of the tank arerequired to fill the chamberwith the solution, of which the final flushcauses the solution to overflow in the syphon tube 26. Thisautomatically discharges into the overflow pipe I2 until syphoning iscut off by the lowering of the level of the solution in the receptacleM. The solution thus discharged gravitates to the bowl and the nextflushing oper ation produces an additional amount of the solution andserves to cause a recurrent syphoning of the solution to the overflowpipe.

Adverting to the modification shown in Figures 5 to 'l'inclusive, thevariation in the structure consists in' providing a cup 29 around thetop portion of the tubular cylinder 30. The cup constitutes a reservoirwhich is filled with water enteringthe cylinder in the refilling of thetank. The eduction tube 3| in this case has its lower extent offset soas to lead into the cup, as depicted in Figure 5.

The operation of this slightly modified structure is precisely the sameas the preferred construction above recounted.
